I apologize, but I'm going to be "that guy." This story simply isn't true. Creating a poetic narrative to advance a particular moral point is nothing new, but it shouldn't be sold as fact when it's fiction. The dude they're talking about isn't even in the picture. His bullfighting career ended after he got paralyzed. He didn't walk away from it- whether or not he might have at some point, he didn't because he got paralyzed by a bull. This picture is apparently showing a common gesture of defiance by a matador for a bull. Yeah, I'm aware that this comment will likely never be read.
